Description

Hand-held instruments for transferring film, such as adhesives, coatings, or colored materials, attached to the back strip wound on the supply reel

In hand-held instruments, the length of the film, i. Therefore, this supply must be replaced after the film is exhausted. Replacing only the supply and winding reels with the back strip is not possible because it is difficult to handle the reels winding the back strip and, in particular, it is difficult to join them together in the housing. Used back strips are easily removed because they can be easily separated from the associated supply and winding reels, but the use of these individual replacements is difficult because they can introduce errors that can affect the legitimate function of the instrument. One possible way to solve this problem is to arrange the supply reel, the winding reel, and the back strip in the replacement cassette so that the replacement is simply done after the supply is exhausted. Such a device is for example disclosed in DE 36 44 946 C2. In this known design, the replacement cassette includes a backing strip with a backing strip, as well as a backing device for pressurizing the backing strip on the object as well as protruding forward from the housing of the instrument. When the film is transferred to the object, the strip is pulled back around it.

In this known technique, the material is consumed because at each replacement time of the material, the supply reel with the back strip and the winding reel as well as the attaching device with the related parts are consumed.

It is an object of the present invention to provide a mechanism as described in the preamble in which the supply reel and winding reel together with the back strip can be replaced at low cost and effort.

This object is achieved by claim 1 of the claims.

In the device according to the invention, a loading aid is provided for receiving the reel and the back strip in essentially the same mutual arrangement with the reel and the back strip in the housing. In this way, it is possible to move the reels and back strips from the loading aids to the positioning parts of the associated bearings and housings by the position of the loading aids that match the reel and back strips with the arrangements described above. Therefore, the loading aid acts as a means to fix the reel and the back strip on the one hand in a position consistent with the arrangement in the housing and on the other hand displaces the reel and the back strip from the delivery state to the working state in the housing of the small appliance. It is possible.

The instrument according to the invention provides the following advantages. On the one hand, as the replacement cassette does not need to meet any further stability and functional requirements, the material is consumed because the loading aids that merely hold the reels and back strips in a specific arrangement are formed as temporary devices with a simple and lightweight construction. Is significantly reduced. At the same time, the loading aid can form a packaging means for the reel and the back strip, which means that no special packaging means are needed. The loading aid, together with the reel and back strips, can be arranged in various ways at the delivery start position where the reel and back strips can be inserted into the housing. On the other hand, it is possible to visually align the loading aid in the delivery start position. In this regard, features such as marks or edges of the loading aid can be used to recognize the correct delivery start position compared to the relevant marks or edges of the housing. It is also possible to arrange a positioning device, such as a pluggable socket, between the loading aid and the housing so that simply inserting the loading aid into the positioning device will always be in the correct starting position.

In the functional state within the instrument, the back strip can slide on the attaching device around the attaching device pre-installed on the loading aid in the form of an arch loop. To this end, the loading aid has a guide element that ensures the position of the loop when the spool is moved to the housing and ensures that the loop moves on the attaching device. In this connection, it is also possible to bear the loop externally or preferably internally within the scope of the invention for the induction element. Such support means are sufficient to stabilize the loop for the delivery process so that the loop can move on the attaching device during movement without any difficulty. The guide element of the loading aid has a shape suitable for the attachment device such that the wedge shape of the loop can be preset in such a way that it can move without any difficulty on the attachment device during movement. In this relationship, since the guide element of the loading aid is slightly further from the reel than the attaching device, the loop in the delivery state surrounds the attaching device with some activity. Such activity can be eliminated by some manual action of the winding reel or automatically removed when the instrument is used, and no problems arise because the winding reel is driven at a winding speed greater than the recovery speed of the back strip. .

After delivery of the reel and back strip, the loading aid may be treated with a low material containing structure or alternatively may be regenerated by carriers and bearings and delivery means.

The present invention and the various advantages achievable by the present invention will be described in more detail below in conjunction with the preferred embodiments and figures.

The instrument has a box-shaped housing 2 that is easily and comfortably sized by hand. The housing 2 has a flat structure with a wide face 3 and a narrow face 4 which are substantially parallel to each other. The functional housing can be arranged flat or with the top edge as in the case of this embodiment. In the cavity of the housing 2, a reel 5, a winding reel 6 forming a supply portion together with a back strip 7, an attachment device 8, and a supply reel 5 and a winding reel 6. A driving device 9 acting between the elements is arranged.

The housing 2 is composed of two parts, namely, a bottom portion 2a and an upper portion, the lower portion 2a having a wide sidewall 11 and a narrow peripheral wall 12, and the top portion having a wide sidewall 13. Having a function as a cover 2b, the upper and lower parts can be joined to each other by a closing device such as the locking device 14. The two parts of the housing can be connected to each other by hinges 15, which hinges 15 are arranged opposite to the attaching device 8 on the rectangular end of the housing 2.

The attaching device 8 is formed by a wedge-shaped pressing part or a attaching part 16, and the attaching device 8 is a method in which the wedge part 16a protrudes out through the opening 17 in the peripheral wall 12. It is mounted on one of the two housing parts. The apex of the wedge is formed by a straight tip 18, which in the case of the housing according to the invention extends transversely to a wide surface, at the ends of the two support surfaces 16b of the wedge. Attachment 16 may be formed as a part of one of the housing parts or as an additional structure that can be connected to one or two housing parts by a plugging socket in a secure locking manner.

In order to mount the reels 5, 6, a bearing mounted as a single part on one side of the two wide sidewalls of the housing is provided in the form of hollow sleeved bearing shafts 19, 21. In this embodiment the bearing shafts 19, 21 are arranged on the cover 2b, and the cover 2b may have a small transverse edge 12a for secure locking engagement with the peripheral wall 12. . The attaching portion 16 is also mounted inside the lid 2b.

Functionally, the housing 2 is configured such that the tip or vertex 18 is positioned on one side of the housing and the housing protrudes slightly downward, for example on an object 23 such as paper lying on a support. Can be pressurized.

The back strip 7 has an adhesive, a coating or a colored material on its outer side (lower side in FIG. 1). The strip is wound on the supply reel 5 and wound on the reel 6 from the bottom of the attachment 16 and the tip 18 when working with the instrument 1. In operation, if the instrument 1 is moved backwards in the direction of the arrow 24, the layer of material 25 in the glue 16 is pressed on the object 23 because of the adhesive force and attached to the object so that the back strip ( 7) The back strip 7 is unwound from the supply reel 5 and wound around the reel 6 by the drive 9. The transmission rate of the drive device 9 is selected large enough so that the winding rate of the circumferential winding reel 6 to be wound is equal to or greater than the circumferential unwinding ratio of the feeding reel 5. This results in the so-called "advance" of the winding reel 6 such that the back strip portion 7a extending between the supply reel 5 and the winding reel 6 has a constant tension. In this regard, the drive 8 is designed to ensure a constant "slippage", that is to say that the tension of the back strip 7 does not exceed a predetermined value.

The drive 9 can be formed by direct friction or toothed engagement on the reel walls 26, 27 or by drive belts, each of which is designed to avoid excessive extension of the back strip 7. May be "overridden". For the sake of simplicity, the drive 9 is shown simply by an arrow. The reels 5, 6 consist of a hollow cylindrical reel arrangement 28, from which the two reel walls 26, 27 extend radially outward so that the unwinding and winding space for the back strip 7 is provided.
